Information display structure, and vehicle station and barrier equipped with said structure

ABSTRACT

An information display structure includes a stationary part to be secured upright on or against a support; securing means for securing the stationary part; and at least one information display screen connected to the stationary part, extending in front of same, and having a visible front display face.

This application claims priority to International Application No.PCT/EP2013/075891 filed Dec. 9, 2013 and to French Application No.1262176 filed Dec. 17, 2012; the entire contents of each areincorporated herein by reference.

The present invention concerns:

-   -   firstly, an information display structure including:        -   a stationary part to be secured upright on or against a            support,        -   securing means for securing the stationary part, and        -   at least one information display screen connected to the            stationary part and extending locally in front of same, the            screen having a visible front display face,    -   secondly, an elongate barrier erected on the support which is        horizontal, such as a station platform where a transport vehicle        passes (in particular a train for transporting passengers), the        barrier standing between an accessible front side and an        inaccessible rear side and including, along its length, in        particular several information display structures of the above        type,    -   and also a station through which the transport vehicle passes,        the station having a platform and providing accesses to the        platform for passengers wishing to access the vehicle in the        station, each access extending along an axis, the station        including, along the platform, several information display        structures.

It will have been understood that the information display structurecited in the first instance is a structure of the general type that isseen in train stations, metro stations and airports for displayingadvertisements on their display boards of 40 inches and more (42 inches,70 inches, etc.).

A problem is linked to the maintenance and siting of these structures.

A proposed solution is that mobility means are disposed between thestationary part and the display screen, or a facade provided in front ofthe display screen, in order to permit a movement of the display screenor of the facade with respect to the stationary part between:

-   -   a closed position of the display screen or of the facade, with        same positioned in front of or against said stationary part,        this closed position being the operational position in which the        screen of the from display face is visible from in front of the        structure,    -   and an opened position of the display screen or of the facade,        allowing access for maintenance:        -   behind the facade or the display screen,        -   or to a rear face of the facade or of the screen.

A latch or a lock will advantageously secure the closed position.

In particular, if the aforementioned display structure is to beintegrated in a barrier for protection/exclusion, which is solid exceptat the site of one or more movable doors, such as a platform barrier ina metro station or train station (then often called a barrier withentrance doors) or for example a barrier in an airport hall separatingthe public area from a flight arrivals area, it may be advantageous forthe barrier effect to be permanently effective.

It is then recommended that the stationary part of the display structureincludes:

-   -   a stationary framework to be secured to the support by at least        some of the securing means, and    -   a solid or substantially solid block fixed to the stationary        framework by second securing means and closing the rear of the        screen or of the display structure, in the closed position.

To facilitate production, assembly and maintenance, it is furtherrecommended that all or some of the following are provided:

-   -   the solid block and the stationary framework together include, a        priori along the barrier, a solid or substantially solid panel        and a frame which at least partially surrounds it, the mobility        means being disposed between the frame and the display screen or        the facade,    -   the display structure includes a movable peripheral structure to        which is fixed the display screen and which preferably carries        some of the mobility means,    -   the mobility means includes hinges disposed vertically, locally        along the stationary part and one of the lateral sides of the        facade or of the movable peripheral structure,    -   the display structure includes electrical or electronic        components for operating the display screen, at least some of        which components, with the display screen, are connected to said        movable peripheral structure so as to be movable with the        latter,    -   the display structure includes a front pane which is situated in        front of the display screen or of the facade and which is        connected to one or the other, the front pane being mounted so        as to be movable with the display screen or the facade.

In an alternative to the above, it is also proposed that the displaystructure:

-   -   includes electrical or electronic components for operating the        display screen, which components are fixed to the stationary        part,    -   and that the display screen is a touchscreen in front of which a        facade pane is movable with respect to the stationary part,        preferably without another pane in front of the screen.

Thus, the opening of the pane will give access to the components, or atleast to some of them that will not have been organized so that theymove with the movable (a priori glazed) facade.

Now as regards the abovementioned elongate barrier which is equippedwith several information display structures, it is recommended that itincludes, along its length:

-   -   at least one movable door leaf in order to open and close a        passage, at this location, between the accessible front and        inaccessible rear sides,    -   at least one stationary block to which the movable door leaf is        connected mechanically and in parallel with which the leaf        slides, the stationary block, which is adjacent to the leaf,        enclosing a space in which is disposed at least one of the        following components: a motor for motorizing the movable door        leaf, a leaf drive device positioned functionally between the        motor and the leaf, a device for locking or unlocking the leaf        in an opened or closed position, and an end-of-travel abutment        for the sliding of the movable door leaf,    -   a stationary structural framework to which belongs the or each        stationary block and which is fixed to each stationary part by        the securing means for securing the stationary part, and    -   means for securing the structural framework, which are fixed in        the support, the information display structures for their part        being situated at a distance from the or each leaf, and their        front display faces preferably being visible on the accessible        front side.

Each stationary block will be able to be replaced by or be integratedwith a safety door equipped with an anti-panic bar system and mountedmovably on a stationary surround, the safety door laterally borderingthe movable door leaf, which will then slide parallel to it. Thestationary surround will then belong to the structural framework.

To combine safety, practical maintenance and information, it has beenenvisioned that the anti-panic bar system is functionally connected toreleasable securing means between the structural framework and thestationary part, which will then be defined by the safety door, suchthat this safety door can open, when a push is exerted on the anti-panicbar, even in the locked position of the locking means provided forselectively locking and unlocking the releasable securing means.Provision is further made that at least one of the information displaystructures is fixed to at least one of the safety doors.

On these barriers, the stationary structural framework will veryadvantageously be provided with (fixed) transparent panes at a distancefrom the zones where the display structures will be mounted.

Thus, especially in this case:

-   -   the display zones will not interfere with the zones of transit        of the persons passing by the door leaves,    -   and, on the platform or for example the hall where the barrier        is erected, the persons present will be able to have easy and        safe access to said displayed information on the display        structures, without losing sight of their environment: arrival        of a train at the station or of a person in the arrivals hall of        the airport, etc.

It is further recommended that, along its length, the structuralframework of the barrier includes upright lateral posts, between two ofwhich is disposed at least one display structure, a display screen, orthis display screen and the facade, preferably with transparent panesbetween other pairs of lateral posts, on each side of a displaystructure.

It is also recommended, for safety reasons, that the information displayfacade includes, in front of the display screen, at least one glazedpanel through which the information will be seen.

It is also recommended that, along the barrier erected on the support,electricity supply cables are provided which are connected to thedisplay screens and/or to at least one of said components, the cablespassing through the support, at a distance from each leaf and stationaryblock or safety door (or, in this latter case, through the hollow postof the frame where the pivot shaft passes, since this is a zone thatreams stationary when the door pivots).

The electrical connections will thus be facilitated, by making theinstallations easier without the need for a centralized connection onthe barrier.

It is also recommended that, for safety reasons and for good managementof the flow of persons in the area around the barriers:

-   -   the or each stationary block has, along the barrier, a free        surface which is adjacent to the space for housing the        components and which could be glazed and transparent, and the        front display face of at least some of the information display        screens is larger than the free surface, such that the display        screens are sited at a distance from the stationary blocks        and/or:    -   each barrier occupies the entire length of a station platform        where a transport vehicle passes, and it includes:        -   two first sets of first and second stationary blocks            extending along the barrier, and        -   two second sets of first and second movable door leaves,        -   with the display screens distributed:            -   on the one hand, in screen groups disposed side by side,                toward the central part of the length of the platform,                between the two second sets of first and second movable                door leaves,            -   on the other hand, disposed individually, more laterally                along the platform.

At least in this case, it is also recommended that the screen groupdisposed side by side toward the central part of the length of theplatform has, along the length of the barrier, a length greater than thelength of each second set.

To limit the costs without adversely affecting safety and to simplifymaintenance, it is further recommended that, in front of each displayscreen, the display structure includes, along the barrier, a single panein the direction of its thickness.

As regards now the station through which transport vehicles pass andwhich has a platform and provides accesses to the platform forpassengers wishing to access the vehicle in the station, each accessextending along an axis, the following is recommended as installation:

-   -   the station will include, along the platform, several        information display structures of the above type or a barrier,        the display screens being distributed:        -   on the one hand, in screen groups disposed side by side,            toward the central part of the length of the platform,            between the two groups of movable leaves and stationary            blocks,        -   on the other hand, disposed individually, more laterally            along the platform, the screen groups disposed side by side            being offset laterally with respect to the axis of each            access.

Here too, safety and good management of the flow of persons in the areaof the barriers will thus be promoted.

According to another aspect, it further recommended that in the stationthe display screens can preferably be distributed:

-   -   on the one hand, in screen groups disposed side by side, toward        the central part of the length of the platform, between the two        groups of movable leaves,    -   on the other hand, disposed individually, more laterally along        the platform than the first ones, at least some of the display        structures of these second display screens being additionally        provided with interactive operating means connected to remotely        situated processing means for permitting man-machine interaction        which allows a user situated in front of one of these second        screens to transmit a request to the processing means, via the        interactive operating means, and to obtain a return of        information on the second display screens.

Other features and advantages of the invention will become clearer ifnecessary from the following description which is given solely as anon-limiting example and in which reference is made to the attacheddrawings, in which:

FIG. 1 and 2 are perspective views of an inventive display structure ina first embodiment and a second embodiment, respectively, when opened;

FIG. 3 and 4 show such a display structure when closed and in anexploded view, respectively;

FIG. 5 shows the display structure from FIG. 4 in a three-quarters frontview, when assembled and opened;

FIG. 6 shows a station, for example a metro station, of which theplatform is provided with a barrier equipped with display structures ofFIGS. 1-5;

FIG. 7 shows the detail VII from FIG. 6;

FIG. 8 and 9 show, respectively from in front and from behind whenclosed, a first embodiment of an entrance door that may belong to aplatform barrier imagined here.

FIG. 10 shows from behind, when closed, a second embodiment of anentrance door that may belong to a platform barrier imagined here, and

FIG. 11 shows a view of what can be the front side of a safety door fromF1G. 10 and an alternative to the solution of FIG. 2.

FIGS. 1-3 in particular show an information display structure 1according to a solution proposed here.

They include:

-   -   a stationary pan 3 to be secured upright on or against a        support, a priori a floor 5,    -   means 30 for securing the stationary part, and    -   at least one information display screen 7,700 connected to the        stationary part and extending in front of it, said screen having        a visible front display face 7 a.

Mobility means 9 are disposed between the stationary part and thedisplay screen 7,700 or a facade 11 provided in front of the displayscreen 7,700.

This will permit a movement of the display screen 7,700 and/or of thefacade 11 with respect to the stationary part between:

-   -   a closed position of the display screen or of the facade, with        same positioned in front of or against said stationary part 3,        this closed position being the operational position in which the        front display face is visible from in front of the structure        (side labeled AVT, as in FIG. 3),    -   and an opened position of the display screen or of the facade        permitting access for maintenance:        -   behind the facade or the display screen,        -   or to a rear face, respectively 11 b and 7 b, of the facade            or of the screen.

Mobility rotation has been envisioned in particular, as is illustrated.A relative mobility by translation from front to rear and inversely, ontelescopic rails perpendicular to the screen, is also possible forexample.

It must be understood that “stationary part” is a part that can occupy astationary position along the platform, unlike the display screen 7,700and/or the facade 11 which are kinds of doors or movable covers. Itshould be noted, however, that all or part of the “stationary part” canitself be movable (for example in relation to the stationary structuralframework 33, for example via hinges and a disengageable lock (forexample engaged on the stationary structural framework 33 which in soniccircumstances would make it possible to open the stationary part 3 andthe display screen 7,700 and/or the facade 11 together.

As is shown FIGS. 1 and 2, it is recommended that the stationary part 3includes:

-   -   a fixed framework 13 to be secured on the support (or to an        intermediate supporting structural framework), for example by at        least some of the securing means 30, and    -   a solid or substantially solid block 130 fixed to the stationary        framework by second securing means 31 and closing the rear (AR)        of the screen or of the display structure in said closed        position (FIG. 3).

It will also be seen that it may appear useful that the solid block andthe stationary framework include respectively a solid or substantiallysolid panel 131 and a frame 132 which at least partially surrounds it,the mobility means 9 preferably being disposed between the frame and thedisplay screen or the facade.

To facilitate production, assembly and maintenance, it is recommended ata movable peripheral structure 15 is furthermore provided to which isfixed (by securing means 150) the display screen 7,700 and whichpreferably carries a part 9 a of the mobility means (for example a maleor female branch of hinges); cf. FIGS. 1 and 4.

The complementary part 9 b of the mobility means will be fixed to thestationary framework 13, in particular the frame 132 (FIG. 2) or the (aninner edge of the) block 130 (FIG. 4).

As illustrated, it is recommended that the mobility means 9, 9 a, 9 binclude hinges disposed vertically along the stationary part and alongone of the lateral sides of the facade (FIG. 2) or of the mobileperipheral structure 15 (FIG. 4).

To operate the display screen like an LCD panel, the display structure1, 100 includes electrical or electronic components such as thoseillustrated in FIG. 4.

For easier access and compactness, it is recommended that the electricalor electronic components 17 are at least in part, with the displayscreen 700, connected to said movable peripheral structure 15, so as tobe movable with the latter, as is shown in FIG. 1 (securing arrangements150). These components 17 will then be able in particular to be fixedintermediately to a plate 19 mounted behind the screen 700 and itselffixed to the peripheral structure 15 (securing arrangements 190).

In this case, it is recommended that ventilation means 21 are mountedwith the mobile part (peripheral structure 15 and/or frame 132) and arefixed to the frame.

Alternatively, if only the facade is movable (FIG. 2), it is recommendedthat:

-   -   the aforementioned components 17 remain, at least in part,        stationary, mounted against/with the front face of the block        130,    -   and that the same applies to the screen 7,    -   and preferably to the ventilation means 21.

FIG. 2 moreover shows that the components 17 for operating the displayscreen 7 are fixed to the stationary part 3 and this screen has atactile facade. In front of it there is only a single facade pane 11,movable with respect to the stationary part, preferably without anotherpane in front of the screen. The opening of the pane 11 gives access tothe components and to the front face of the screen, as is shown in FIG.2.

The ventilation means 21 cool the components 17 and blow air between thescreen and the facade pane 11.

As ventilation means 21, two lines of ventilators are recommended,respectively at the top and bottom of the display structure, in order toventilate the screen and components situated between them with thestructure closed and operational.

Generally, for simple maintenance and protection of the screens, it isrecommended that the information display structures 1,100 include afront pane 23 situated in front of the display screens 7,700 or thefacade 11 and connected to one or the other, the front pane beingmounted so as to be movable with the display screen or the facade.

In any event, it will be preferable that a single (transparent) paneprotects the screen as a facade, whether its own pane (FIGS. 1 and 3) oran attached pane movable without it (FIG. 2). Likewise preferably, itwill be possible to choose an arrangement in which, in front of eachdisplay screen and at a distance therefrom, along the barrier, thelatter includes a single pane in the direction of its thickness, as inthe figures. This will facilitate maintenance and may for example avoidventilation between the two panes, two such panes were to exist in frontof one of the screens 7,700 (that of the screen+one of the panes 111erected in front).

FIGS. 6 et seq. show an elongate barrier 10 equipped with severalinformation display structures 1,100 with only part of the barriersometimes being illustrated.

The barrier 10 is erected on the support 5 which receives it and whichis horizontal.

In practice, this will typically he a station platform which passed by atransport vehicle 25. However, it is also possible to imagine aseparation between public area and a restricted access area, for examplein an airport.

The barrier 10 stands between an accessible front side (AVT) and aninaccessible rear side (ARR).

It includes along its length:

-   -   at least one movable door leaf 27 a (or 27 a, 27 b) for opening        and closing a passage 29, at this location, between the        accessible front side and inaccessible rear side, respectively,    -   at least one stationary block 31 (or 31 a, 31 b) adjacent to the        leaf, the information display structures 1,100 which are        situated at a distance from the or each leaf and of which the        front display face is preferably visible on the accessible front        side,    -   a (stationary) structural framework 33 to which belongs the or        each stationary block 3 and which can be fixed to each        stationary part by the means 30 for securing the stationary        part,    -   and means 31 for securing the structural framework, these means        31 being fixed in the support 5.

The information display structures 1,100 are situated at a distance fromthe or each leaf 27 a, 27 b. Their front display face is visible on theaccessible front side AVT.

As a variant, provision could be made that the front display face isvisible on the inaccessible rear side ARR (tracks 35 in FIG. 6), butfrom the other side of these tracks (platform 50 in Figure. 6). Thus,from the other platform 50, the information on the screen would bevisible from the platform 5 through the transparent panes 111 mounted (apriori fixedly) on the stationary structural framework 33 between thezones of the barrier that are provided with display structures 1,100.

The (or each) movable door leaf 27 a (or 27 a, 27 b) is connectedmechanically to the stationary block 31 a (or 31 a, 31 b), parallel towhich and therefore along which it slides, in the direction of sliding37.

In the case of a stationary block called a functional block, the latter,or at least one of the two 31 a, 31 b, will enclose a space 39 in whichis disposed at least one of the following components 41: a motor formotorizing the one or more movable door leaves, a drive device for theone or more leaves, which is disposed functionally between the motor andthe leaf, a device for locking or unlocking the leaf (or leaves) in theopened or closed position and an end-of-travel abutment for the slidingof the movable door leaf. This situation is that of the example in FIGS.8 and 9 which show, respectively, the side AVT (platform side oraccessible side) and the side ARR (track side 35 or inaccessible side).

Alternatively, provision is made that the (or each) movable door leaf 27a (or 27 a, 27 b), thus provided for a normal access or exit via thepassage 29, is bordered laterally by one or two safety doors 43 a, 43 bthat extend along the barrier, parallel to the latter, as is shownschematically in FIG. 10.

Each lateral safety door is equipped with a known safety system withanti-panic bar 45 that it suffices to push so that the door opens (hereby pivoting) from the inaccessible side (ARR) to the accessible side.

The or each safety door is mounted so as to be movable on a stationarysurround 46, for example by hinges 48 having a common vertical axis;FIG. 10.

In addition, one or each safety door 43 a and/or 43 b is equipped withan information display structure 1,100, or at least one screen 7,700 ofwhich the visible face 7 a is directed toward the front AVT (theplatform). FIG. 10 shows, on the side ARR, the solid or substantiallysolid block 130 fixed to the stationary framework.

FIG. 11 again shows a number of elements from FIG. 2, although this is asolution in which the stationary part 3 remains stationary as long asone has not opened the releasable securing means 310 established betweenthe structural framework 33 and this stationary part 3, which will thenbe a door, since it is connected to the structural framework by pivotingmeans 451 on a vertical axis 451 a.

Preferably, these pivoting means 451 and the axis 451 a are situated ona vertical lateral edge of the frame 132, a priori on the side where thefacade 11 pivots (on a parallel axis) if it is provided. Locking means453 are provided on the stationary part 3 for selectively locking andunlocking the releasable securing means. A latch or a lock with theirlinkages will be suitable. If the facade 11 is provided, releasablelocking means 455 separate from the means 453 (and for example lockableon the frame 132, but not on the framework 33) will permit access to thepanel 7/7 a without possible access to the other side (rear), exceptingspecific opening of the means 453.

Comparing FIGS. 10 and 11, it will be understood that each door 43 a, 43b will be able to correspond to the solution of FIG. 11: The stationarypart 3 (occasionally door) will then be provided with the safety system450 with anti-panic bar 45 (inaccessible side, for example to the rearof the block 130 fixed to the frame 132). This anti-panic bar systemwill be connected functionally to the releasable securing means 310(which will expediently be of the magnetic lock type), such that thisstationary part 3 “occasional door”(or 43 a, 43 b in FIG. 10) can openeven in the locked position of the locking means 453, when a push isexerted on the anti-panic bar 45. The push on the bar 45 will bringabout the actuation of the linkage 457 (or of a relay) without thelocking of the means 453 prohibiting it, thereby freeing the securingmeans 310. The occasional door 3 will then open, specificallyexclusively to the front (platform or AVT), the pivoting means 451 beingdisposed accordingly.

FIG. 11 also shows that, in order to permit the pivoting of thestationary part 3, the electricity supply cables 53 will expediently bepassed through the corresponding vertical post 132 a of the frame inorder to power the components 17. The means 30 fix the structuralframework 33 to the support (such as the ground) 5 at a distance fromthe stationary part 3.

In another aspect, FIG. 10 shows (as also in FIGS. 8 and 9) that themovable door leaves 27 a, 27 b are glazed (transparent pane 111), ascould be the panel laterally adjacent to the (each) safety door 43 aand/or 43 b (this can be the block 130 of FIG. 11).

In this case, the components 41 operating the one or more leaves 27 a,27 b (for opening them, closing them, locking them and unlocking them)will be housed, at least substantially, in an upper caisson 47 whichtops the door module 49, this module including the movable leaves andthe lateral safety door. The caisson extends longitudinally along thedirection 37, thus also above the leaves, both in the opened positionand also the closed position of these.

As is shown in FIGS. 7-9 (in which the structure 1 or 100 is justsymbolized), provision is moreover made that, along the length of thebarrier 10, the structural framework 33 includes upright lateral posts51, between two of which is disposed at least one display structure 100,a display screen 700 (solution of FIG. 1 for example), or this displayscreen and the facade 11 (solution of FIG. 2). The posts 51 willpreferably be hollow girders or poles with a closed (rectangular) orU-shaped cross section.

It is clear that such lateral posts 51 can be provided in the case of abarrier with safety door(s) 43 a, 43 b, as is envisioned in FIG. 6.

As has already been mentioned, it is further recommended, formaintenance and safety, that the information display facades along thebarrier comprise, in front of each display screen 7,700, at least oneglazed panel through which the information is seen.

Moreover, for supplying electricity to the screens 7,700 and/or some atleast of the electrical or electronic components 17, provision is made,at least in the case of a barrier 10 without upper caisson 47, that thisbarrier includes, along its length, electricity supply cables 53 whichare connected to said display screens and/or to at least one of saidcomponents. The cables 53 pass through the support 5, at a distance fromeach leaf 27 a, 27 b, and stationary block if it exists (cf. FIG. 8 and9).

As is shown in FIG. 2, the electricity supply cables 53 are connected toa main electricity supply (cable) which, in particular if the barrierhas no upper longitudinal caisson 47, will pass under the support 5,here a platform under which a volume is reserved for the passage inparticular of electricity cables.

It is thus possible to avoid congesting the area of the passages 29.

The barriers without an upper longitudinal caisson 47 will typically bebarriers referred to as “half-height” barriers, in which, with the oneor more leaves opened, the space above these is free (case of FIGS. 8and 9).

If the barrier is provided with an upper longitudinal caisson 47 in oneor more aligned sections (case of the barriers referred to as“full-height” barriers), the main electricity supply cable 55 will thenpass through the caisson 47 where the electricity supply cables 53 ofthe electrical or electronic components 17 will be joined (even of thecomponents 41 for operating the leaves), as is shown schematically inFIG. 10.

To promote especially the movement of persons, in particular in theaccessible zone 5, or even between the accessible zone and inaccessiblezone, and if, as shown schematically in FIG. 6, the barrier 10 occupiesthe entire length of a station platform 5 through which a transportvehicle 25 passes, it is further recommended that this barrier includes:

-   -   two first sets of first and second stationary blocks 31 a, 31 b        extending along the barrier, and    -   two second sets of first and second movable door eaves 27 a, 27        b,    -   with the display screens 7,700 distributed:        -   on the one hand, in screen groups 70 (FIG. 6) disposed side            by side, toward the central part of the length of the            platform, between the two second sets of first and second            movable door leaves (designated 270 in FIG. 6),        -   on the other hand, disposed individually, more laterally            along the platform; see also FIG. 6.

For the same purpose, it is recommended that the group of screensdisposed side by side toward the central part of the length of theplatform has, along the length of the barrier, a length L1 greater thanthe length L2 or L3 of each second set; cf. FIG. 6 in which L2 and L3rather show a width dimension, although this makes no change to theproportions indicated above.

Another point treated concerns the preferred arrangement of theinformation display zones on screens. In this context, it is recommendedthat the or each stationary block 31 a (or 31 a, 31 b) has, along thebarrier, a free surface 3100 which is adjacent to said space 39 providedfor housing the components 41, and which could be glazed and transparent(as in FIG. 8 and 9: panes 111), the display screens 7,700 then beingsited at a distance from the one or more stationary blocks, with in thiscase, for at least some of them, a front display face larger than thatof the free surface.

In an embodiment as in FIGS. 8 and 9, however, provision can be madethat a structure 1,100 with a screen 7,700, as in one of the solutionsof FIGS. 1-5, is fixed next to the stationary block 31 a, 31 b, in amanner thus adjacent to it, and the supply of the electrical orelectronic components 17 can then be made via the space 39.

Such an installation of the screen structures 7,700, all at leastpotentially of a size greater than Lb.times.lb, will improve thevisibility on the screens, will distance the persons situated in frontof the screens away from the leaves and from their immediate proximity,will limit the weight of the leaves and will avoid complicating theiroperational safety.

As regards a station itself now, such as the one in FIG. 6, maytypically be defined as a zone:

-   -   through which a transport vehicle 25 passes,    -   having a platform 5, and    -   providing accesses 57 to the platform for passengers wishing        access the vehicle in the station, each access extending (or        opening onto the platform 5) along an axis (such as 57 a and 57        b for the two accesses schematically depicted), the station        comprising, along the platform, several information display        strictures 1,100.

The display screens are distributed as above, namely:

-   -   on the one hand, in screen groups disposed side by side, toward        the central part of the length of the platform, between two        groups of movable leaves and stationary blocks,    -   on the other hand, disposed individually, more laterally along        the platform.

An important point is that the one or more screen groups disposed sideby side are laterally offset with respect to the axis of each access 57.

This will distance the persons situated in front of the screens awayfrom the axis of each access, which is favorable as regards safety andas regards access for maintenance,

Another aspect of the station concerns the fact that the display screenswill preferably be distributed:

-   -   on the one hand, in screen groups 70 disposed side by side,        toward the central part of the length of the platform, between        two groups of movable leaves and stationary blocks or safety        doors (43 a, 43 b),    -   on the other hand, disposed individually, more laterally along        the platform than the first ones (such as those of width L2 or        L3).

As will be understood from FIGS. 2, 6 and 7, at least some of thedisplay structures of these second display screens will preferably beprovided with interactive operating means 59 connected to remotelysituated processing means 61 to permit man-machine interaction allowinga user situated in front of one of these second screens, such as thoseunder the broken lines in FIG. 7, to transmit a request (viatransmitting/receiving means) to the processing means, via theinteractive operating means 59, 63, and to obtain a return ofinformation on these second display screens.

Preferably, the processing means 61 and the local interactive operatingmeans 59, 63 (situated on the platform) will exchange, viatransmitting/receiving means and/or local processing means, informationpermitting wireless communication.

It will further be noted that other inventive aspects are consideredlikely to respond as an invention to identified technical problems.

It concerns the following:

-   -   an elongate barrier erected on a support which is horizontal,        such as a station platform where a transport vehicle passes, the        barrier standing between an accessible front side and an        inaccessible rear side and including along its length:        -   at least one movable door leaf in order to open and close a            passage, at this location, between the accessible front and            inaccessible rear sides,        -   at least one stationary block to which the movable door leaf            is connected mechanically and in parallel with which said            leaf slides, the stationary block, which is adjacent to the            leaf, enclosing a space in which is disposed at least one of            the following components: a motor for motorizing the movable            door leaf, a leaf drive device positioned functionally            between the motor and the leaf, a device for locking or            unlocking the leaf in an opened or closed position, and an            end-of-travel abutment for the sliding of the movable door            leaf,        -   several information display structures, which are situated            at a distance from the or each leaf and which each comprise            at least one information display screen having a front            display face preferably visible on the accessible front            side,        -   a stationary structural framework to which the display            screens are fixed directly or indirectly, and        -   preferably means for securing the structural framework,            which are secured in the support.

With a multimedia barrier of this kind, it will be possible to improvethe information for users, without forcing them to move away from theedge of the platform (where the barriers of the “entrance door” typeshown here are normally situated), and without risking a situation wherepeople looking at the screens gather opposite the door leaves.

It is recommended that, as has already been mentioned, electricitysupply cables, along the barrier erected on the support, are connectedto the display screens and/or to at least one of the components foroperating these screens, the cables passing through the support at adistance from each leaf and stationary block.

The electrical connections will thus be facilitated, by making theinstallation easier without the need for a centralized connection on thebarrier.

It will furthermore be recommended that. as has likewise already beenmentioned:

-   -   the or each stationary block has, along the barrier, a free        surface which is adjacent to the space for housing the operating        of the screens and which could be glazed and transparent, and    -   the front display face of at least some of the information        display screens is larger than the free surface, such that the        display screens are sited at a distance from the one or more        stationary blocks.

Thus, and as has already been mentioned:

-   -   the display zones on screens will not interfere with the zones        of transit of persons passing by the door leaves,    -   and, on the platform or for example the hall where the barrier        is erected, the persons present will be able to have easy and        safe access to the displayed information, without losing sight        of their environment: arrival of a train at the station or of a        person in the arrivals hall of the airport, etc.

Stations set out as has been mentioned above, but with this type ofbarrier, would be suitable and are here considered as in particularresponding to the same problems, or affording the same advantages, asthose mentioned above.
